CAW-TRUCK..

SPECIFICATION forming part of Letters Patent No. I789,511, dated May 9, 1905.

Application iiled February 20, 1905. Serial No. 246,462.

To (LZ2, 1071/0771, it Netty concern.-

Beit known that I, IVILLIAM Voss, a citizen of the United States, residing at I/Vilming'ton, Newcastle county, Delaware, have invented a certain new and useful Improvement in CarrIrucks, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, forming part of this specification, in whichw Figure 1 is a top plan view of a portion of my improved car-truck. vational view of the same, and Fig. 3 is a sectional view through one of the side frames.

This invention relates to a new and useful improvement in car-trucks designed cspeciall y for use in connection with electric motors, the object being to construct a truck of the character described with a short wheel-base and a minimum height of frame.

By my improved construction a minimum height of the frame is obtained by locating the spring to one side of the journal-boxes instead o'f over the journal-boxes, as is usually practiced. A low frame so produced is very desirable in both open and closed cars, as it permits the use of a single step to the car.

I/Vith these objects in view the invention consists in the construction, arrangement, and combination of the several parts of my device, all as will be hereinafter described and afterward pointed out in the claims.

In the drawings the side lframe of the truck consists of a top bar 1, bent at its ends, said ends being' connected by end angles 2.

3 indicates a spring-supported motor suspension-bar which is preferably bent so as to carry the motors outside of the axles, the bent portion of this bar providing the necessary room for such suspension.

4 indicates the bottom bar of the side frame, which is secured at its ends to the bent ends of the top bar 1.

5 indicates the end casting, to which the transom members 6 are secured, said end casting serving practically as a strut for the trussed side frame, of which the top bar 1 is the compression member and the bottom bar t is the Fig. 2 is a side eletension member. The transoms 6 are pro- 50 vided with suitable bearings 7, in which are mounted links 8, supporting the spring-plank 9. Between the links 8 this spring-plank carries the bolster-supporting springs IO, preferably elliptical springs, on which is carried the bolster 11, said bolster having' the usual side and center bearings and. being of ordinary construction.

12 indicatesa connection-plate riveted tothe top bar 1 and having inwardly-extending por- 6o tions riveted to the transom members (5.

The end casting or strut 5 forms a support for the inner ends of arms 13, which are pivotally connected thereto. These arms 1.3 carry the journal-boxes 14, in which the wheel-axles 6 5 are mounted. The outer ends of arms 13 are provided with spring-seats 15, in which are arranged springs 16, bearing at their upper ends against appropriate seats 17, secured to the top bar 1.

18 indicates guide-plates arranged on the free ends of arms 13, said guide-plates coperating with rubbing-plates 19 on the inner vfaces of the bent portions of the bar 1.

l/Vhen the car-body is supported by the bol- 7 5 ster 11, its load is transmitted through the springs 1() onto the transoms G and thence to the side frames. The links 8 accommodate the lateral swaying movement of the car-bod y, this construction being well known in what 8o are commonly termed swing-motion trucks. Ihe arms 13 being pivoted to the end casting 5 will yieldingly support the load through the springs 16, whose vertical movementis guided by the plates 18, as will be readily understood. 8 5 It will be observed that the springs are arranged outside of the axles, thus enabling' the truck-'frame to be lowered, the pivotal connection of the arm to the strut improving the spring action. The location of the springs 9o outside the journal-boxes also enables the use of springs of greater height than is possible if said springs were arranged above the boxes, and in addition the distance between the springs is greater than the distance between 9 5 the axles, which contributes to the steadiness of the iframe in service, particularly under those conditions where the forces are applied first to one end and then the other by the kiek or reaction of the motors or by the application of the brakes, which latter, however, is not so considerable.

I am aware that changes in the construction, arrangement, and combination of the several parts of my device can be made and substituted for those herein shown and described without in the least departing from the nature and principle oi:l my invention.

Having thus described the invention, what is clailned as new, and desired to be secured by Letters Patent, is-

i l. In a car-truck, the combination with a compression member whose ends are bent so as to provide vertical faces, a tension member, a strut, and journal-boxes pivotally connected to the strut and guided in their vertical movements by the vertical faces of the compression member; substantially as described.

2. In a car-truck, the combination with a bar l bent at its ends, an end casting, a bar 4 secu-red to said end casting and to the bent ends of said bar l, journal-boxes pivotally connected to said end casting, means for guiding said vertical boxes in their vertical movement, and springs for cushioning the vertical movement of said journalboxes; substantially as described.

3. In a car-truck, the combination with a side frame, of journal-boxes pivotally mounted upon said frame, means for guiding the free ends of said journal-boxes in their vertical movement, and springs arranged to one side of said journal-boxes; substantially as described.

4. In a car-truck, the combination with a trussed side frame, of journal-boxes pivotally connected to the strut of said trussed side frame, means for guiding the free ends oi' said journal-boxes, and springs arranged to one side of said journal-boxes; substantially as described.

5. In a car-truck, the combination with a side frame, of arms 13 pivotally mounted thereon, journal-boxes carried by said arms, means for guiding'the free ends of said arms, and springs cooperating with said arms, said springs being arranged adjacent the free ends of the arms; substantially as described.

6. In a car-truck, the combination with a trussed side frame whose compression member is bent to provide guideways at its ends, arms pivotally connected to the strut of said side frame, journal-boxes carried by said arms, the free ends of said arms coperating with said guideways, springseats on the arms, and springs interposed between said seats and the compression member; substantially as described.

7. In a car-truck, the Acombination with a trussed side frame, ofarms pivotally connected to the strut of said trussed side frame, journal-boxes carried by said arms. springs coperating with said arms outside the journalboxes, the free ends of said arms being guided by a member of thetrussed side frame, and motor-supporting bars yieldingly carried by the ends of said trussed side frame, said motorbars being' offset to enlarge the distance between the same 'and the truck-axles; substantially as described.

In testimony whereof I hereunto a't'x my signature,in the presence of two witnesses,this 15th day of February, 1905.

ITILLIAM VOSS.
